摘要: 为解决城市特大断面隧道照明能耗高、质量低的问题,以重庆海天堡城市隧道(内轮廓面积145.91 m2)为例,采用照明数值仿真分析的方法,引入灯具安装距高比参数,研究特大断面隧道布灯方式、灯具配光曲线、安装纵向间距等照明设计参数对隧道照明质量的影响。结果表明: 在同一距高比下,照明质量指标值如路面平均照度、路面照度总均匀度、路面中线照度纵向均匀度值等均随布灯间距的增大呈先上升后下降趋势;当距高比为1.5时,采用中央布灯方式、纵向间距为10.5 m、配光曲线为对称非蝶形时照明质量指标值最高,其路面平均照度、路面照度总均匀度、路面中线照度纵向均匀度与原方案相比分别提高了35%38%24%;选择合适的布灯方式与配光曲线的搭配组合,有利于提高特大断面城市隧道路面照明质量。

Abstract: The lighting in superlarge crosssection urban tunnel is high in energy consumption and low in lighting effect. Accordingly, a case study is conducted on the Haitianbao urban tunnel with an inner contour area of 145.91 m2 in Chongqing, China. Based on the lighting numerical simulation analysis method, the parameters of lighting installation spaceheight ratio are introduced to investigate the influence of lighting design parameters, such as lighting distribution mode, lighting distribution curve, and installation longitudinal spacing, on tunnel lighting quality. The results show that: (1) Under the same spaceheight ratio, the indices of illumination quality, such as the average illumination of road surface, the total uniformity of illumination of road surface, and the longitudinal uniformity of illumination of the middle line of road surface, increase first and then decrease with the increasing spacing of lamps. (2) When the spaceheight ratio is 1.5, the illumination quality index value reaches the highest when using central lighting mode, the longitudinal spacing of 10.5 m, and symmetrical and nonbutterflyshaped light distribution curve. Compared with the original scheme, the average road illuminance, the total uniformity of road illuminance, and the longitudinal uniformity of road midline illuminance are increased by 35%, 38%, and 24%, respectively. (3) It is beneficial to improve the lighting quality of urban tunnel pavement with large crosssection by selecting an appropriate lighting pattern and light distribution curve.
